lMy invention relates to air deflectors, and refers particularly todevices of this character suitableA for use with open windows.

` One object of my device is an air deflector simple in construction and of low 'costi of production. l

Another object of my device Ais an air de ectorwhich can be'packed and shipped in fiat form, thus Saving space and "cost yof package and overcoming the danger of breakage incident to devices of fixed anguf' lar fOIIllaton. y

Another object of my device iS en air deflector having a wire netting of transparent, air impervious material, the free, "sharp ends of the wire being protected to prevent damage, or injury, to a person handling the device and which will at the same time present an attractive and pleasing appearance.

A consideration of my specification and its accompanying drawings will show that my device possesses all of the abovementioned and other desirable attributes.

I have found that paper fiber board is a Z5 strong, durable and inexpensive material for devices of the character described and I take advantage of these properties of this material as well as the possibility of bending under certain conditions without breakage.

I have further found that wire netting covered with a transparent air-impervious material yis a most efficient material from which to form the transparent portions of my device, because of its cheapness, freedom from breakage and durability.

As the free, cut edges of wire netting present a serious objection to its use, because of its liability to scratch, or injure, the hands of the user, IY have found a means whereby this danger maybe avoided, while at the same time the appearance of the device is greatly enhanced over one having exposed wire ends.

In order to accomplish this last mentioned desirable quality, I compress, or impress, the edges of the paper fiber board around Vthe opening to be covered by the netting, and then insert the netting within the recess thus formed, the cut edges of the netting being below the surface of the device, and thus protecting the user from danger incident to the sharp ends of the netting wires. This form of construction also enhances the appearance of the device and makes it more attractive. i

The device of my invent-ion, therefore, is

.a Cheap, effective, showy, and attractive am defieet'or. Y i 1 In the accompanying drawings illustrating modified forms of tliedevice of my in- Ventron, similar parts are designated by slmilar numerals. 'i

The 'particular form of the device of my invention shown in the accompanying drawings comprises a blank, or sheet, of paper fiber board 10, having the two score-lines 11, 11 and'1111; allowing the two triangu lar shaped end pieces 12, 12 to be bent at right angles tothe base 13 witho-ut tearing the blank.

Within the base 13 are two recessed openings as 14, formed by impressing, or forc ing outwardly, the edge 15 of the base surrounding the opening, thus forming arecess 16.

Reposing within this recess is a sheet of wire netting 17 covered with a transparent flexible material which allows' the passage of light but prevents the passage of air or water.

The netting 17 is maintained in place by throughthe netting 17 and the recessed p0rtion 15 and the base 13.

In the modification shown in Figure 5, the netting'is maintained .in position by wirestitching 19.

The operation of the device is as follows:

The blank is folded, or-bent,"along the score-lines 11, 11 until the triangular end pieces 12, 12 are at right angles to the base 18. The end pieces 12, 12 are then inserted between the opposite sides 20, 20 of a window-frame 21 and attached thereto by means of nuts, screws, or other suitable fastening means 22, 22.

The device, therefore, presents a cheap and y effective air deflector, comprising a blank oI paper fibert board capable of being shipped, er' stored, 1n compact, flat ferm, and which 1,650,237 PATENT oFFicE.

a plurality'of wire staples 18, 18 passing f and easily attached to a Window frame. TheV construction of the device being such that the raw edges of the Wire netting are WithinI a base recess, thus presenting an attractive appearance and preventing the damages in cident to an exposed edge of sharp Wire ends.

I do not limit myself to the particular size,

shape, number, arrangement or material of part-s as shown and described as thesev are given simply as a means for clearly describing the device of my invention. Y

What I claim is p 1.
